Username and Display Name Moderation API
Paxmod screens usernames, display names, comments, and short kids submissions before they go live. You send each string in one API call. Kids media, education platforms, classroom tools, and games use it for pre-publish screening, not only game chat.
username moderation API for kids and education platforms
Paxmod screens usernames, display names, and short user text before they go live. You send each string to POST /api/v1/text in the message field. Kids media, education platforms, classroom tools, and games use it for pre-publish screening. Try the API free.
display name filter API vs word lists
Word lists over-block innocent names (the Scunthorpe problem) and miss leetspeak. Paxmod is a display name filter API: one call returns flagged or not_flagged so you can block or review before publish. Organisations can shadow-test on existing names first. Talk to us about a pilot.
The problem with short user text
Names and short comments look small. The risk is not. Harmful content slips through lists, and lists punish normal users.
Short strings hide risk
Usernames and display names can hide sexual content, phone numbers, addresses, slurs, and leetspeak bypasses in a few characters.
Word lists over-block
Simple blocklists catch innocent names. That is the Scunthorpe problem: a place name or real name trips a substring filter.
Small teams cannot watch live
Classroom tools, kids sites, and education platforms cannot review every comment and name change in real time.
How it works
Call the same Paxmod text endpoint used across the docs. Put the username, display name, or short comment in the message field. Many teams use a stricter project for names than for chat.
Request

Frequently asked questions
Can I use Paxmod only for usernames and display names?
Yes. Send each username or display name to the same text endpoint used for chat. Many teams create a stricter project just for names, then a separate project for comments or short submissions.
Is this only for game chat?
No. Paxmod is API-first trust and safety infrastructure. Kids media, education platforms, classroom tools, and games all use the same text API for pre-publish screening.
Does Paxmod replace a word list?
It can. Word lists alone over-block innocent names and miss leetspeak. Paxmod scores the string you send and returns flagged or not_flagged so you can block, rewrite, or queue for review.
Is Paxmod built for COPPA requirements?
Paxmod is COPPA-oriented. It helps you screen usernames, display names, and short text for younger audiences. Meeting COPPA is a legal call about your full product and data practices. Talk to your counsel.
Can we test on our own data first?
Yes. We can run a shadow test on existing names and comments before you cut over. You see how the API would have acted without changing live traffic.
Where is data hosted?
Talk to us about data handling and hosting region requirements. Procurement and legal can review a service agreement before you go live.
